Synthesis of poly(arylimidazoliums) PAImXY(#). X and Y represent alkyl chains and # represents the analogous model compound illustrated in Fig. 1. Five polymers were synthesized: PAImMM(10), PAImMB(11), PAImEE(12), PAImPP(13), and PAImBB(14), possessing the same architecture as compounds 10–14, where M = methyl, E = ethyl, P = propyl, and B = butyl
